Title: Same genus, different specific epithet? Post by: buffyl13 on Mar 20, 2012 Drosophila melanogaster and Drosophila simulans are fruit flies that are identical in appearance except for small differences in their genitalia. Hybrids can be produced, but they are sterile. On a basis of this information you can conclude that D. melanogaster and D. Simulans meet the criteria to be considered;
1. different biological species and different morphospecies 2 . different biological species but same morphospecies 3. same biological species and different morphospecies 4 . same biological species and the same morphospecies Title: Same genus, different specific epithet?

Title: Same genus, different specific epithet? Post by: bufi on Mar 20, 2012 Tell your professor that geneticists should keep their noses out of taxonomy. Dobzhansky's "biological" species concept is worthless for most organisms (extinct, asexually-reproducing, or both) and has crapped up the education of all too many biologists. If the prof is a geneticist, I wouldn't tell him this until you have gotten your final grade, though.
Oh, and real biologists (not geneticists) call these "sibling species". Title: Re: Same genus, different specific epithet? Post by: bio_man on Aug 16, 2012 Tell your professor that geneticists should keep their noses out of taxonomy. lol |
